Tmobile Version has AT&T LTE support, and unlocked bootloader?

So far it looks like the Tmobile S4 has LTE/HSPA+ support for AT&T, and no real signs of a locked bootloader. Anyone else plan on buying that version and unlocking it if the bootloader is in fact unlocked?
Does anyone know of any apps that would test the LTE/HSPA+ bands the phone is capable of? I want to go into a Tmobile and use a test unit to see if I can get service with my LTE AT&T SIM.

Edit: Well, it looks like I'll be getting the Tmobile variant unsubsidized and use it on AT&T. Tmobile will unlock the phone if you pay the total cost up front. I just need to find a replacement back cover to rid myself of the stupid Tmobile logo on the back... lol.

If I had the money to buy the S4 outright for full price, I would just get an i9505.
EDIT: Spoke too soon. The i9505 doesn't support AT&T's LTE bands.

Can you post info on the source? I was also curious about this but i was thinking if we changed the radios like they did in the past that maybe we could get something working?

I put the info in the OP that I have so far; the LTE/3G radios are reported to support all of AT&T's bands. The bootloader, I'm going off of a guess since I don't think that Tmobile could afford to bribe Samsung to lock their bootloaders for them.

HMM, ok thanks for the info so far. I might have to go out and pick one up and test it.

Looks like the T-Mobile version has all the same bands and some extra ones added in. For instance the at&t only has lte bands 4&17. The tmobile version has LTE bands 1,2,4,5,7&17. Will T-Mobile unlock their phones for u??

I'm feeling like a newbie today cause I have my new T-Mobile Galaxy S4 in front of me & still playing with new features after 3 hours.
Tell me how to check to see if bootloader is unlocked and I'll do it.
Also trying to remember where we go to unlock the developer tools. Only remember that it must be clicked 7 times?
Just remembered, Settings.About Device>Build Number <Click Build Number 7 times, back out and Developer options magically appears.
Now i can go into it and toggle USB debugging. Now I only feel 95% newbie.

So .. How do I get TMoble 4G on my HTC One X
What do I have to do get off Edge and onto Tmobile 3g/4g. I have the unlocked HTC One X ... What apps are there, and what steps needs to be followed.

Has anybody tried their T-Mobile phone on AT&T yet?
If so, I have a couple of questions.
1. Can you use the T-Mobile phone to wireless tether (become a wifi hotspot) on AT&T's network? The AT&T version can be used to tether (with a simple hack). I was just wondering if a different .APK would be needed to do the same with the T-Mobile phone on AT&T's network or if the T-Mobile phone already has an APK installed that works on AT&T's network?
2. I realize an existing AT&T sim card can just simply be placed into the sim unlocked T-Mobile phone for it to work, but how would I go about changing the imei and other phone info that AT&T has in their system about the phone? In other words, would AT&T cause problems with anyone using a T-Mobile phone on their network even if the person paid full price for the phone and it is unlocked? Would it be better to have them change the system information at a store versus over the telephone?
3. It is reported that the T-Mobile phone works fine on AT&T's LTE network, has anyone verified this and does the phone show LTE when on AT&T's LTE network?
Thank you for any replies. Hopefully this information can help people decide if they want to buy the T-Mobile S4 to use on AT&T or not.

You can, for now, use PDAnet for tethering.
As far as changing the phone to appear as "unknown" to AT&T's system, don't do it without a backup of your /efs folder. I don't recommend doing it either because it's not really worth changing things around to hide that you're on a Tmobile phone, because for the most part, they don't care as long as you're paying them your monthly bill. I personally know a friend who has used her unlocked HTC Amaze on AT&T without issue (she was stuck to 2G speeds). The only way for you to have an "unknown" phone on your account is to use an international model phone such as the HTC one or the i9500 (unconfirmed that the i9300/i9500 model is entered into AT&T's system, I only hèard a rumour that AT&T has the IMEI of those phones in its system). My i9100 currently shows up as "unknown" in my bill statement.
I took a screenshot, but I don't have a link of the LTE working conformation (attached). I won't be getting my phone until I am on holiday in New Hampshire so that I can avoid the sales tax on purchasing the Tmobile variant. I would ask my parents to buy it for me, and I send them the money, but they have no technological skills whatsoëver close to asking/knowing what to ask for at the Tmobile store. Sorry guys, lol.

Which model to buy for full freedom

I am on ATT but I am tired of ATT BS and locked bootloaders and ROM work arounds. I want to be able to use international ROMs. Plus I want to have my ATT LTE.
I want freedom to have me device my way and with any carrier sim. With this said money is not the issue. So what do I buy. If I am reading things right the answer is a T-Mobile Version and then cancel the contract and put my ATT SIM in the Note 3.
Can anyone confirm or advise?

Want your cake (international version) and eat it too (non-international LTE) AND complain because getting both requires a bit of work? LOL
No carrier is going to let you have full freedom w/o you going behind their back (i.e. unlocking bootloaders and custom ROMs)

The T-Mobile appears to have an unlocked Bootloader and unlocked if paid in full. So that sounds like a clean unit to me. That I am free to load Intonational ROM's etc...

If you don't mind 32GB only of internal storage, which effectively translates into ~24GB of user available space - T-Mobile GN3 is your best bet. Pay in full, to get it unlocked and put your AT&T sim into it. Then you will have unlocked bootloader, no carrier network lock, no regional lock and it will work with AT&T LTE. You will be able to use international roms as well, as long as they're not for the octa-core version. You will also be able to flash AT&T modem to it, if you wish.

I just got the T-Mobile Note 3 from Negri (unlocked) It is $689 with no tax here in CA

I want to order a Note 3 from Negri to use it with AIO. I would like to have the unlocked bootloader but I'm worry about something I read in another thread here (Note 3 Carrier Selection):
"The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals."
What if ATT is using 1700 in my area for LTE? I will have the unlocked bootloader and no LTE? Where can I find what frequencies ATT is using in what areas? I made some searches without luck.
Any help will be appreciated.

Some search without luck? You've got to be kidding me! I have personally posted AT&T's LTE frequencies in at least 3 threads in Note 3 forums. It takes about 2 seconds to google a wiki page with LTE frequencies by carrier worldwide...FYI AT&T operates it's LTE network on both bands 4 and 17 in most areas. However, I don't understand why do you think there is a problem with AT&T & T-Mo using the same frequency in a certain area. There are 2 absolutely independent carriers, each with their own towers and your phone will get service from a carrier, based on whatever SIM you put in. What difference do these overlapping frequencies make to you?

I did find information about the frequencies used by each carrier. What I was looking for is what frequency is used in a given area, say near my house. Maybe that is not the right question since I'm new to all this problem.
In another thread (Note 3 Carrier Selection) people is recommending to buy the TMobile version over the ATT version even if you want to use it with ATT (AIO). Because the bootloader in TMo may be unlocked. But then cheols46 posted this:

I have 2 HTC One from each carrier and while AT&T version will pick up LTE at my house with the AT&T sim card in it, while T-mobile version only picks up HSPA+ with the AT&T sim card. It really depends on the tower frequency you use in your area.

I want to know if that will happen to me if I buy the TMo version to use it with AIO.
Thanks in advance for any help you may provide.

That guy is getting only HSPA with AT&T SIM card because his APN for AT&T LTE is not configured correctly on the T-Mo phone. He probably didnt change the APN settings, or maybe T-Mo stock firmware doesnt even have those settings, since the network didnt support LTE when that phone was bought?
If your phone is configured correctly, and you use AT&T SIM you should get LTE service.

Will you advice to buy the sim unlocked TMo version instead of the ATT version, because of the unlocked bootloader and the support for TMo bands (again this is just something I read)? I'm planning to use it with AIO but after spending all that money it will be good to know that I could use it with TMo if I wanted.

If i were you I'd wait a week or two, until other people do it, and you can find enough feedback on how well things work. The question, you should be asking yourself is not a choice between T-Mo vs AT&T version, but T-Mo vs international LTE version with unlocked bootloader, because getting AT&T one with locked bootloader will severely cripple what you can do with your phone. Keep in mind if you have any LTE version with unlocked bootloader you should be able to flash AT&T modem onto it, once it becomes available, regardless of what LTE bands it currently supports.

Unlock S5 From Sprint To Tmobile?

I recently got the S5 on sprint and im beyond disappointed with sprints new spark and lte network out here in NY. Im considering going to Tmobile since there lte speeds are crazy good and connection is steady out here. My question is can i get my phone unlocked and bring my sprint version phone over to Tmobile? I was told by a Tmobile rep that my phone would go down to 2g speeds and its not guaranteed to even get lte. Which i find hard to believe since since my phone has the option to also go on GSM/UMTS. Whats your guys thoughts on this?

Correct. Sprint uses different frequency ranges, so unlocked or not it's just not going to communicate.
ATT and T-Mobile work due to the overlap. In fact, for a while there ATT was going to purchase T-Mobile before the FCC put a halt to that.
Glad too as T-Mobile is now shaking up the market and forcing (encouraging?) Verzion and ATT to try and adopt similar measures in order to maintain customer base.

I dont think this is correct. Albeit S5 is a different phone, but I unlocked 4 SPH-L720 S4's from Sprint to Tmobile no problem using the following thread: http://forum.xda-developers.com/showthread.php?t=2530610
If S5 could use the same methods, you would get 3G and HSPA+ on the Sprint S5 using a TMobile SIM.
I was able to get LTE using a TMobile SIM on a Sprint S4 by using DFS to edit the NV to enable AWS 1700 LTE Band in NV items, then flashing the TMobile HOS and MODEM bin files - along with copying the *ril*.so libraries to the system/lib directory. This ultimately allowed me to select the LTE/WCDMA/GSM option in Mobile Networks.
Not many people know about this but I found it in an i337 thread on how to unlock AWS on a S4.

Has anyone comfermed this? To my knowledge the Sprint/Verizon phones are not cross compatable with AT&T and T-mobile. Some verizon phones are the exception but basicily its a no go from CDMA phone to GSM tech.

confirm
i can confirm the sprint s4 does work on tmobile with a bit of editing and following the gsm domestic tutorial on xda, however this part about the modem.bin and hlos isnt confirmed and i have done this and ended up hard bricking my devices and had to jtag to repair them. ive tried many times and always bricked so i say no go.
this forum is for the sprint s5 and i would hope we can find a loophole to get it gsm unlocked. any ideas? ive tried a few things but no luck

Theres alot of incorrect information here. The latest Sprint phones using sim cards ARE ABLE to use T-Mobile and AT&T as long as GSM is in the hardware. I dont own the S5 but for those blinding others with frequency talk I'm tired of seeing, read it and weep:
http://www.phonescoop.com/phones/phone.php?p=4408
Sprint S5 supports GSM. Now of course no LTE on T-Mobile due to the lack of the 1700 frequency,
but your 4G will be fine. Depending on where you live, you may not even care about LTE over 4G.
Sure, Sprint locks the darn thing up to avoid it getting into the hands of other domestic carriers, but
just as the Sprint Note 3 and my Sprint LG G2, a workaround has been invented. For the G2 it was as
"borrowing" the stock T-Mobile LG G2 firmware and tweaking it to boot up on our LS980. We have
about 3 different tastes of working unlocked roms, not only sticking to T-Mobile, but other carriers
reported working such as Metro PCS and AT&T. So my guess is that the S5 may need a similar
treatment, nobody wants Sprint honestly. The first 14 days (brought in my own LG Optimus G LS970)
I was with them service was glorious here in NYC. But after the 14 day "trial period" ended I was
DAMNED into horrible service, constant 3G instead of 4G, etc. Thanks to refusing to make payments
due to the disgusting service, my GS4's IMEI is basically crap, so I sold it in the same week I got it.
I should have never swapped it out for the LG OG...
Honestly, I'll thank every OP I see that "unlocks" the Sprint version of any phone for domestic GSM
use. Their silly Sprint Spark is useless, why introduce something new when they dont even have full
4G coverage here in the USA? And their agents sound like "AI" controlled cyborgs: "Oh we're sorry to
hear that, your zone is scheduled to be recieving 4G soon." Yeah right. I feel sorry for those who suffer
in other states.
ANYWAYS sorry for drifting off topic. The recap here is that the Sprint S5 IS capable of domestic GSM with some modding.
And also that I hate Sprint.

Any Updates on this
Does anyone have any news on this? I have a S5 from sprint and want to use it with tmobile or other gsm carrier. any1 have any updates on the UCCI deal i read about somewhere? I have the spc phone is rooted what do i need to do? cant bring up the service menu to change things there.. kind a lost pls help

..

lease has anyone found a solution for enabling aws bands on galaxy s5? i have the at&t active version unlocked and rooted using on tmobile but i get only edge :/

What is the verdict? Is there anyone who knows you can use it on any network? I am getting mine tomorrow and am unlocking it. Is there a way to test if they will work on any network? I have many sim cards from diff carriers.

There have been a lot of threads about this, so clearly few are even bothering to search the forum for existing threads and the wealth of information in them.
Sprint is a CDMA system like Verizon & USC. CDMA per se is incompatible with GSM, which is what most of the world uses. The Sprint S5 only supports some of the most common GSM frequency bands and moreover will have a locked bootloader and SIM.
Sprint will not unlock the SIM (actually SPC code) to allow using it with other domestic carriers. You can find third party vendors that will "SPC unlock" your Sprint phone. But then you will find that Sprint's S5 won't support any of the LTE bands on other CDMA or GSM carriers and misses some GSM bands too.
Nor can you use custom ROMs, kernels or recoveries in the normal manner due to the locked bootloader. You could probably use the Verizon Safestrap method to emulate a limited palette of custom ROMs, but you would have to do your due dilligence there and look into the details.
In short, if you jump through enough hoops, you can use a Sprint S5 on another carrier like TMobile. But it will always be marginal. You won't get LTE data speeds, you will see more congestion than those using native handsets, due to your reduced number of bands. And you may have no coverage at all in some fringe areas served by a TMB band that your handset doesn't have.

The limitation of what "bands" the radio will cover are software defined. if you look around. you can find a way to modify those defined rules.
to allow it to use 1700 LTE. although the legality may be questionable as the FCC approval for that model was not tested with the LTE. The baseband chip/radio still supports the band with the software changes

Sprint is a CDMA system like Verizon & USC. CDMA per se is incompatible with GSM, which is what most of the world uses. The Sprint S5 only supports some of the most common GSM frequency bands and moreover will have a locked bootloader and SIM.
Sprint will not unlock the SIM (actually SPC code) to allow using it with other domestic carriers. You can find third party vendors that will "SPC unlock" your Sprint phone. But then you will find that Sprint's S5 won't support any of the LTE bands on other CDMA or GSM carriers and misses some GSM bands too.
Nor can you use custom ROMs, kernels or recoveries in the normal manner due to the locked bootloader. You could probably use the Verizon Safestrap method to emulate a limited palette of custom ROMs, but you would have to do your due dilligence there and look into the details.
In short, if you jump through enough hoops, you can use a Sprint S5 on another carrier like TMobile. But it will always be marginal. You won't get LTE data speeds, you will see more congestion than those using native handsets, due to your reduced number of bands. And you may have no coverage at all in some fringe areas served by a TMB band that your handset doesn't have.

What in the heck? Who fed you this bologna? Do you work for Sprint? Cause I have various complaints for you if you do. My SPRINT G2 running a T-Mobile G2 stock rom which is unlocked DOMESTICALLY works perfectly fine with T-Mobile's 4G. I don't think many people care about LTE, getting off of Sprint alone is a huge leap for mankind (in this case G900P owners). And as it was mentioned, there are ways to get that nice LTE band for various devices with simple mods, problem is that it is NOT widely recognized yet and very few people know that the possibility exists because of various misleading posts that "its all in the hardware" and fingers being pointed at Qualcomm's techniques. Yes there is a possibility for a domestic unlock, sure there might not be LTE for it, but most people will be content with the fact that they can use their expensive locked down phone with another carrier. Honesty Sprint devices would be better off being sold for less than carriers that actually DO allow domestic unlocks. Why do we pay over half a "K" for a phone that in reality we do not completely have full rights over? Why do other carriers alow domestic unlocks and Sprint wants to be greedy and lock in all of their customers with shady contracts and decieving bills?
Thats why many of us including myself would be beyond grateful if we even get some 3G with another carrier. We have CDMA capabilities, we have GSM capabilities, all we need is some sort of domestic unlock.
There is NO third party unlock code of any sorts that will unlock a phone that is unlocked OTA. Check around for many posts from various foreign users who have gotten stuck with a useless Galaxy S5 that can only be used with wifi thanks to Sprint. Is it their fault? No. It is purely Sprint's fault for being so damn greedy. Thankfully I am hearing news that by February of 2015 all devices will be GSM and have the capabilities to be unlocked for domestic use.
Custom roms, honestly most of us are just unsatisfied with the average and like to go to the unique side. But is Cyanogenmod going to allow us to use Air Gestures and all the other cool features of the S5? Not really. Custom kernels would be nice, but many people only seek then in order to overclock their device, which this device is in particular really doesn't need any more added power (or battery drain) than it already has. Optimization tweaks might be worth it but I dont see it helping. If someone could fix the delayed multitasking transitions (switching from one app to the other at times is delayed a second or two) or the crashing browser without custom roms or kernels, then it is best not to waste time on the development of such things. But then again there are those who prefer stock android in combination with other features such as the AMOLED screen technology, but it is best to look for another device.

Can I use a Tmobile Note 4 on AT&T and vice versa?

Can I use a Tmobile Note 4 on AT&T and vice versa and have it work with LTE?
In other words, is the Note 4 interchangeable with both Tmobile and AT&T LTE service?

yes

Potentially, yes. You could do the reverse, so I can't see why it wouldn't work.

It's showing the same bands to it should work, no one will know until they actually test it. The Note 3 also had the same bands, but some anecdotal reports stated the reception was a bit worse and it didn't hang onto LTE as well. Nothing scientific, just users reporting this so make of it what you will. Personally my business can't take the chance of reception issues so I just bit the bullet and got the ATT version knowing I am saying goodbye to root. Once again this is unsubstantiated, it's just what I got from hours of looking at all the forum posts about using the Tmo Note 3 on ATT.

How about a Verizon Note 4 on AT&T? Verizon is charging almost $150 less for an off contract phone, however I have a mobile share plan with other AT&T phones on contract so I'd need to stay on AT&T if possible...

Is it possible to "unlock" (or whatever the term is) an AT&T phone to use with Tmobile?
I want to use AT&T mainly but when I'm traveling internationally, I want to be able to switch to Tmobile.

Yes you can and the term is "unlock". Just make sure the bands are compatible on your at&t phone with the Tmobile network.

Well, that's what I want to know. Will LTE work on both networks with either or both Tmobile and at&t versions?

I know you can use TMOBILE PHONES on ATT - I assume you can do the reverse -but I don't think you can run TMOBILE PHONES on Verizon - or Verizon PHones on TMOBILE - I say this because the roms created for Verizon were really never very compatible for Tmobile phones ( at least not for me on any of the roms I tried to flash - data didn't work - wifi didn't work - ) so I htink they have different kinds of radios - but I am not a developer so that is only a guess -
USE TMOBILE phone on ATT and you are fine

Yes - as long as you manually add the APNS - but keep in mind the ATT PHONE will have a locked bootloader and it will probably be a while until someone finds a way to root the ATT PHONE - I say this based on what happened with the Note3 and S5 - I assume the same will be the case for ATT NOte 4s

If somebody takes an AT&T phone to T-Mobile, it will get fully functional LTE (as they both use band 4 aws). However, T-Mobile has built most of its 3G network on Band 4 UMTS / HSPA (AWS 1700/2100) which AT&T phones to not support. This coverage footprint is bigger than their current LTE network. The AT&T phone will get Band 2 (1900) UMTS / HSPA in the areas T-Mobile has refarmed.
A T-Mobile phone is fully compatible with AT&T. All T-Mobile phones support bands 2 and 5 for 3G (H+). T-Mobile phones also support AT&T's Band 17 for roaming reasons.
Be advised that if your using a T-Mobile device on AT&T (preferably an LTE device) it may not get the best reception, as AT&T optimizes their modems for their lower frequencies. Last year my T-Mobile Note 3 LTE reception was awful on AT&T. The T-Mobile S5 on AT&T was improved, but not as good as AT&T's own S5's reception.

I am pretty sure I know the answer to this - but if the ATT modem is better for att users - if someone does have a TOMBILE PHONE - why is that we can't flash an ATT Modem on the TOMBILE Phone?
I realize there is a chance of 'brcking" but if the phones are so close to each other anyway - why can't you flash an ATT Modem on a TMOBILE phone? Anyone?.

I'm not sure. But a few years ago there was a guy from Canada using a Rogers device ( I think the S3?) anyway AT&T had just released an update for their S3 and it drastically improved signal strength and data speeds. He took it upon himself to flash only the modem from CWM. The phone rebooted and he had no IMEI number. Therefore his phone couldn't even connect to the network. I'm not sure how or if he resolved it. But that lesson right there made me never flash any carrier's modem on my device.

That would keep me away too - but it's too bad - as much a like as the variants are - it is too bad they are not more interchangeable

Unlock Sprint GS 7 for use on ATT/T-Mobile

I want to purchase a Sprint GS 7 and sim unlock to use on GSM carriers like AT&T and T-Mobile.
What is the process official and other options for sim unlock.
Never had Sprint service before, thanks for your assistance.

First step is to not stick a sprint sim card in the phone. I played around with mine without a sim card and to get the stupid vr game promo i stuck the card in and next thing it did was install all the carrier garbage bloatware automatically and it changes the boot screen and to my understanding it sim locks to the carrier that the sim card uses. Complete bullsh!t I am irate and stuck with all of this garbage bloat courtesy of sprint and the locked bootloader thanks to samsung. Im returning mine

I bought my sprint s7 full price through best buy.
First thing I did was swap the sprint Sim with my AT&T Sim (testing first Sim inserted). Prompted with invalid Sim error.
Appears the sprint phones come with activation software pre-installed that locks it to their network. You need them to unlock it from their end, no unlock codes.
When I put the sprint Sim back in, it didn't install all the bloat. It installs everything if you activate the phone; unactivated Sim, no account.
According to sprint, the phone needs to be activated on the network for 50 days and paid in full to be unlocked. They unlocked mine without meeting those standard because of poor support from a rep before I bought it.

After you get it unlocked, you can just insert any sim (gsm/cdma) after?
I don't see any settings to change the network mode.

I'd like to know the same. I'm traveling over seas in less than two week and would like to use while over seas with the local carrier. Not so much concerned with using it with other carriers domestically though.
I'm also curious if the phone can be used for data on other carries once unlocked. I wonder because with my current Sprint GS5, Sprint unlocked it, but it does not work with data when over seas. Come to find out after a lot of research, there is no solution and everybody with unlocked Sprint GS5s also cannot get data to work without wifi.
OP, you may want to keep that in mind and do your research. If Sprint's GS7 is like their GS5, you will not be able to get data on the phone with other carriers even if unlocked, unless connected to wifi.

Yes, any Sim CDMA or GSM will work. And data works perfectly for me. The s7 is the same device for every carrier where the only thing that changes is the software.
Here's a screenshot of my sprint phone on cricket with data.

With the Sprint model, there will be LTE issues overseas depending on where you go and which carrier you use.

I went to UK in 2013, had my S4 with me and was able to get data. I was not, however, able to get fast LTE speeds. Sprint cripples their LTE bands on purpose for some reason so that they become less useful on many international carriers.

The main difference between models on each carrier are bloatware they add and LTE bands they add and delete. Sprint always gets rid of useful LTE bands like LTE 7 which is a popular worldwide band.

Correct. Cricket is owned by AT&T, a carrier who did not get rid of band 7, despite the fact that they use Sprint's 3G network as well as CDMA. Do you have bands 25 and 26 as well? If so, that would be great!

You're also correct but this is a Sprint S7 network unlocked. And yes, I do. 25 and 26 are the first priority for me.

I don't actually. Knowing this I'm going to focus on attempting to add these bands (toggle them). Trying to get a hold of Sprint currently to get my MSL code.

The Galaxy S7 is DUC meaning it can be unlocked for domestic use, and it will automatically unlock tru a programming update sent OTA after the device has been active on the account(in good standing) for more than 50 days.

For those not in good standing, or who don't feel like waiting, find somebody with a Z3X-box, like myself, on craigslist. $45 (or usually in that area,) takes us 5-10 minutes, don't need root, and doesn't need to be clean. =]

##3282#

Just bought a sprint s7 yesterday since it was cheaper for me and had it unlock from an ebay listing for about $15. It was quick like 2 minutes and easy. Its done remotely on the person's end with your phone connected to computer. I'm using it on Tmobile and is working great. I get lte speeds and call quailty is great. Getting to the service menu above ##3282# you can edit the band priorities so you can have the wanted bands 1st, 2nd, and so forth. Just need the MSL# which they can get you.
If this is against the rules sorry, but just thought I give my experience with unlocking the sprint s7.

I'm trying to find detailed specs without luck, can someone please clarify which LTE bands the Sprint variant of the S7 has?
Please list all that are physically on the radio, and specify if they are actually available for use or blocked.
